[Intel-gfx] [PATCH v4 13/14] arm64: dts: qcom: sc7180: Add support for HDCP in dp-controller

[Sean Paul]

From: Sean Paul <seanpaul at chromium.org>

This patch adds the register ranges required for HDCP key injection and
HDCP TrustZone interaction as described in the dt-bindings for the
sc7180 dp controller. Now that these are supported, change the
compatible string to "dp-hdcp".
